Answer 1

Answer:

Establish the plug flow model of an

electrochemical reactor consisting of two

concentric cylindrical electrodes. The electrolyte

flows axially in the annulus at a volumetric

flow rate Q. The cylinder radii are r, andra

and length L which is shown in the figure .

Answer 2

Answer:

The average of first n natural numbers = (n+1)/2. The average of squares of first n natural numbers = (n+1)(2n+1)/6. The average of cubes of first n natural numbers = n(n+1)2/4.
